unknown. — The larva recalls that of mirijica ; it is everywhere finely felted and besides clad with rather 
long, partly very fine whitish partly somewhat rough black hair. On each side of the first joint there is 
a long prominent hair-pencil, and on the last joint a single pencil showing hindward. These pencils consist 
of black and white hairs, and the tips of the black ones are often light-coloured. The light dorsal spots are 
clad with fine appressed silky hairs. The whole dorsal side is broadly blackish-brown with nine golden yellow 
dorsal spots, the first and last of which are double and elongate, the others being transverse. The sides and 
the whole underside are silvery white. Congo near Mukimbungu. 
Of the two following species only the rjd are known. They are distinguished by the head, the thoracal dorsum, and 
the median band of the forewing being of a bright green colour. 
Ch. viridescens Holl. (29 b). B- The marking of the forewing is best seen from the figure. Hindwing 
above blackish with white fringes, beneath with a red-brown spot between the costal margin and the discal 
cell. Ogowe Valley. 
Ch. antennifera Strd. (29 b) is somewhat larger than Ch. viridescens and has a more brown ground¬ 
colour of both wings; on the forewing the green submarginal band of viridescens is absent, and the costal margin 
of the hindwing above is broadly greenish. Cameroon. 
Ch. albicilia B.-Bak. This species being unknown to me, and of which only the B sex is known, seems 
to be closely allied to the two preceding ones. The description says: frons and antennal shaft dark creamy; 
pectinations blackish. Thorax on the yellowish ground densely clad with olive-green hair, and with a yellowish 
spot on the dorsum. Abdomen dark grey, the long first joints with long olive-green hair, the apex with yellow 
hair. Forewing light yellowish-brown, in the basal half densely covered with fine hair-like olive-green scales, 
and in the marginal area with common grey scales; a slanting dark antemedian transverse line being angularly 
broken at the costal margin, and a similar still more slanting median transverse line. Hindwing very dark 
brownish-grey with white fringes and with long olive-green hair at the base. Lagos. 
The two following species have comparatively still smaller BS the wings of which are above almost uni-coloured 
yellowish-brown or reddish. 
Ch. imparilis Auriv. (= ladbury B.-Bak.). B- Forewing above light greyish-reddish without distinct 
markings (a fine dark postmedian transverse line and a series of submarginal dots which are feebly indicated). 
Hindwing above at the costal margin with reddish, in the middle particularly in the areas 2 to 4 with yellowish, 
and at the hind-margin broadly with greyish-yellow hair. Beneath almost as above, but the forewing in the 
middle (in the areas 1 b to 5) with yellow scales. Head, chest and ventrum light greyish-yellow; thoracal dorsum 
reddish like the forewing; anal pencil yellowish. Antennal shaft whitish, pinnae at least towards the antennal 
apex blackish. Expanse of wings: 30 to 33 mm. $. (29 a). Forewing above light greyish-yellow with two 
brownish-red transverse lines and a similar dot at the end of the discal cell; sometimes also with some brownish- 
red submarginal spots particularly in the areas 5 to 7. The first transverse line before the middle is deeply 
flawed at the costal margin and then almost straight; the second postmedian line is almost rectangular at 
the costal margin at vein 7 and then straight, composed of crescentiform bows; hindwing above golden 
yellow without markings. Both wings beneath yellow, at the bands lighter, greyish-yellow, the markings of 
the forewing very indistinct; hindwing with a brown postmedian transverse streak at the costal margin in 
the areas 7 and 8. 54 to 55 mm. — The larva has long hair-tufts on the first and last segments and varies in 
the colouring from a silvery grey to a greyish-green or lemon-colour; it lives on Combretaceae, particularly 
on species of Terminalia (according to Schultze). Nigeria, Senegal, and also found in the Bugoma Forest 
(L. Albert). 
Ch. bivittata sp. n. (29 a). B- Size and shape of wings very similar to the B °f Ch. imparilis, but at 
once discernible by the fore wing above showing two orange-yellow longitudinal stripes proceeding from the 
base, one of which almost reaches the anal angle in 1 b, whilst the other extends through the discal cell to the 
centre of area 5. Head and upper surface of body as far as the apex of the abdomen covered with yellow 
hair; chest, ventrum and legs grey or whitish. Antennal shaft almost white; pectinations of the basal half 
brown, of the apical half blackish. Fore wing above light greyish-yellow with two fine indistinct transverse 
lines and hardly noticeable dark submarginal dots, beneath at the base blackish, then bright yellow, and at 
the margin lighter, greyish-yellow. Hindwing on both sides of a bright yellow, at the costal margin darker, 
reddish, or beneath reddish-grey with a brown transverse streak at the centre of the costal margin, and with 
whitish-grey fringes. Expanse of wings: 33 mm. £ unknown. German South-West Africa. 
Ch. lutulenta Tams. Of this species being unknown to me only the $ has been described. Body orange 
or ochreous yellow; head and palpi yellowish-grey. Forewing light chrome-yellow, at the costal margin dark 
greyish-yellow, at the base with a large dark grey distally emarginated spot covering almost the basal third 
of the wing; at the end of the discal cell a bright orange, almost circular spot with a light chrome- 
yellow centre; behind this spot a dark grey triangular spot; a broad postmedian grey transverse band and 
a submarginal row of grey spots are more or less united. Hindwing of a bright orange-yellow, at the 
costal margin broadly chrome-yellow, with a narrow, short, grey transverse streak from the centre of the costal 
margin and one nearer to the apex. Both wings beneath light chrome-yellow, partly orange-yellow. Expanse 
of wings: 62 mm. German and British East Africa.
